DAVID LICHTENSTADT AND CHARLES LICHTENSTADT, OF CHICAGO, ILLINOISELECTRIC MAGNETIC MASSAGE-KNEADER.

SPECIFICATION forming part of Letters Patent No. 444,597, dated January13, 1891.

Application filed December 8, 1890. Serial No. 378,927. (No model.)

To all whom/it may concern.-

Be it known that We, DAVID LIOHTENSTADT and CHARLES LICHTENSTADT,citizens of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented a new and useful Improvementin an Electric Magnetic Massage-Kneader, of which the following is aspecification, reference being had to the accompanying drawings, inwhich- Figure 1 is a top or plan view, and Fig. 2 is a centrallongitudinal section.

The object of our invention is to provide an improved electric magneticmassage-kneader for use in all cases of nervous and rheumatic pains andin similar local diseases.

It is the chief object of our massage-kneader to combine electricity andmagnetism with the massage treatment.

Our invention consists in a kneader provided with electric elements,which are adapted to be rolled over the surface to be treated, and inthe magnetic bar upon which said elements are supported, and in thecombination of the various parts, as hereinafter described, and pointedout in the claims.

In the drawings, A represents a frame of metal. Upon this frame of metalis secured an insulated handle B. This handle B may be made of wood,glass, rubber, or other suitable insulating material.

C represents a magnetic steel bar, which is secured in the frame Abymeans of the nuts 0. This steel bar 0 is a permanent magnet, and ishighly magnetized before being inserted in place.

D represents a series of electric elements. Each element D consists of acopper disk (Z and a zinc disk 6. Each disk has a central hole to fitthe bar 0 loosely, and is provided with a number of nipples g, arrangedaround its periphery. The copper disks (1 and the zinc disks 6 of eachelement are soldered together, and the outer surface of each zinc diskis amalgamated with quicksilver in the usual way. Between the severalelements are placed felt pads f, which are saturated, preferably, withdiluted sulphuric acid and glycerine. The elements are placed upon thebar O, which forms the axis in consecutive orderthat is, first a copperand zinc element, then a prepared felt pad f, next a copper and zincelement, and so on to the desired number of elements. As many elements Dmay be used as may be desired or necessary in treating a particulardisease. As shown in Fig. 2, six elements are used, which elements fillthe space between the ends of the frame A; but, if desired to use asmaller number, one or more elements may be omitted and a rubber washerplaced between the last element and the end of the frame A. The numberof elements may be greatly increased by increasing the size of the frameA; but the size shown is preferable for many reasons.

The kneader is used by rolling the elements D over the surface to betreated, and the electricity produced by the elements D and the feltpads f will greatly increase the efficiency of the kneade", as it iswell known that the application of electricity is a cure for rheumatismand similar diseases. The magnetism of the bar C also greatly increasesthe efficiency of the kneader, as magnetism also has been foundeflicacious in the treatment of rheumatism, rheumatic pains, and similardiseases. The nipples g of each element are arranged so that the nipplesupon one disk will come between the nipples of the adjoining disk. Bythis construction a nipple will be in contact with the surface beingtreated at all times.

The handle B may be varied in form and size to suit the convenience ofthe operator. \Vhere the person being treated desires to apply thekneader without assistance, the handle B may be varied in form, so thatthe person can readily apply the kneader to the surface to be treated.

What we claim as new, and desire to secure by Letters Patent, is a 1. Ina massage-kneader, the combination, with a frame A and a bar 0, of aseries of elements consisting of zinc and copper disks arranged uponsaid bar and adapted to be rolled over the surface to be treated, andfelt pads f, interposed between the said elements, substantially asandfor the purpose specified.

2. In a massage-kneader, the combination, with a frame A, of a bar O,permanently magnetized, and rotating disks mounted upon said bar,substantially as and for the purpose specified.

3. In amassage-kneader, the combination,

\vitha frame A and bar-C, of electric elements elements D, mounted uponsaid bar, and felt IO D, consisting of copper disks d and zinc diskspads interposed between the said elements,

6, said disks being provided with nipples g substantially as and for thepurpose specified.- upon their periphery and being adapted to V 7 1 V 35 be rolled over the surface to be treated, and g i felt padsf,substantially as and for the pur- J J pose specified. \Vitnesses:
